APC by Schneider Electric Netshelter SX 48U 750MM Wide Perforated Split Doors Black - AR7157

APC by Schneider Electric AR7157 NetShelter SX 48U Perforated Split Doors

Overview

The AR7157 is a pair of perforated split front/rear doors designed specifically for APC NetShelter SX 750mm-wide 48U enclosures. If you're running a fully populated 48U rack with high-density compute or networking gear, the split-door design here matters: each door swings independently, so you can access the top or bottom half of the rack without opening the full 85.9-inch panel — a practical advantage in tight rows where swing clearance is limited.

These doors ship in black to match the standard NetShelter SX finish and are sized precisely for the 750mm-wide, 48U frame. This is a direct replacement or field-addition component — if you're expanding an existing NetShelter SX deployment or replacing damaged doors, the AR7157 is the part to order.

Key Features

• Split-Door Design: Two independently operable door panels cover the 48U height. In dense rows where a full-height 85.9-inch swing would collide with adjacent racks or a raised floor obstruction, opening only the half you need saves time and prevents accidental contact with neighboring equipment.
• Perforated Panel Construction: Perforations support front-to-back airflow — critical in any rack running actively cooled equipment. Unlike solid doors that force all cooling air around the enclosure, perforated panels allow direct airflow through the door face, supporting hot-aisle/cold-aisle containment architectures without removing the doors entirely.
• 750mm Width Compatibility: Sized for the 750mm NetShelter SX frame specifically. The 48U, 750mm-wide SX enclosure is a common standard in mid-to-large datacenter deployments; this door set fits that footprint exactly without modification.
• 85.9-Inch (2,182mm) Assembled Height: Covers the full usable height of a 48U enclosure. The door height accounts for the frame's structural envelope, not just the 48U of rack space — verify your row height and any overhead cable tray clearance before installing.
• 33.97 lb (15.41 kg) Door Weight: At roughly 34 pounds per door assembly, hinge integrity on the host enclosure matters. Confirm the SX frame's hinge condition before mounting, especially on enclosures that have been in service for several years or have been relocated multiple times.
• Black Finish: Matches the standard NetShelter SX black powder-coat finish for a consistent appearance across multi-rack rows. If your site uses the grey NetShelter SX variant, verify color compatibility before ordering.
• Single-Unit Packaging: Ships as one packaged unit (1 PCE). Package dimensions are 89.02 in × 18.0 in × 8.0 in at 39.7 lb — plan for the package footprint during receiving and staging, particularly in freight elevators or narrow server room doorways.

Integration & Compatibility

The AR7157 is engineered for the APC by Schneider Electric NetShelter SX enclosure line — specifically 48U, 750mm-wide frames. Before ordering, confirm your existing enclosure's unit height (42U vs. 48U) and width (600mm vs. 750mm); these dimensions are not interchangeable between door SKUs. If you're sourcing doors for a 42U or 600mm-wide NetShelter SX, a different APC door part number applies.

For integrators managing mixed rack populations, this door set pairs with the standard rack enclosures category of APC NetShelter SX hardware. It does not include locks, blanking panels, or cable management accessories — those are sourced separately. If airflow management is a concern in your deployment, pair these perforated doors with rack airflow management accessories such as blanking panels for unused U-spaces to prevent recirculation.

Installation requires no tools beyond what's standard for NetShelter SX door removal and re-hang. APC's enclosure hinge system supports field door swaps; consult your rack planning guide for hinge-pin removal procedures specific to the SX line.

Frequently Asked Questions

Q: What enclosure is the AR7157 compatible with?

A: The AR7157 is designed for APC NetShelter SX 48U, 750mm-wide enclosures. It is not compatible with 42U frames or 600mm-wide SX variants — verify both the U-height and width of your enclosure before ordering.

Q: Are the doors sold as a pair or individually?

A: The AR7157 ships as a single packaged unit (1 PCE) containing the split-door assembly for one enclosure. The split design means two panels are included to cover the full 48U height.

Q: What is the assembled height of the AR7157 doors?

A: The assembled door height is 85.9 inches (2,182 mm), covering the full structural envelope of the 48U NetShelter SX enclosure.

Q: Do the perforated doors affect cooling performance?

A: Perforated doors support front-to-back airflow and are compatible with hot-aisle/cold-aisle containment. They allow direct airflow through the door face, unlike solid doors that restrict airflow to the enclosure's sides and top.

Q: How much do the AR7157 doors weigh?

A: The door assembly weighs 33.97 lb (15.41 kg). The packaged shipping weight is 39.7 lb (18 kg).

Q: Are locks or blanking panels included with the AR7157?

A: No. The AR7157 includes only the perforated split-door panels. Locks, blanking panels, and cable management accessories are sourced separately from the APC NetShelter SX accessory line.

The AR7157 comes up regularly when a NetShelter SX 48U row needs to be refitted or expanded — either because original doors were damaged during a move, or because a site is converting solid-door enclosures to perforated for better airflow compliance. The split-door configuration at 85.9 inches total height is the detail that separates this from a simple door swap: in rows with less than 90 inches of clear swing arc, you can't practically open a full-height panel without bumping adjacent hardware.

Technical Highlights:

• Split-Door Geometry: Independent upper and lower panels across the 85.9-inch (2,182mm) height mean you only open the half you're working in — reduces swing intrusion by roughly 50% in tight rows.
• Perforated Construction: Allows direct airflow through the door face rather than routing all cooling around the enclosure perimeter — directly supports containment architectures without requiring door removal during high-load periods.
• Weight Distribution: At 33.97 lb (15.41 kg), the assembly is substantial. Field installs on aging SX frames should include a hinge-pin inspection before hanging — a worn hinge on a fully populated 48U rack is a liability.

Deployment Considerations:

• Package dimensions run 89.02 × 18.0 × 8.0 inches at 39.7 lb — confirm freight elevator and doorway clearances at the delivery site before scheduling the install, especially in basement or sub-floor data rooms with standard 84-inch doorframes.
• The AR7157 is sized exclusively for 750mm-wide, 48U NetShelter SX frames. A 600mm-wide or 42U enclosure requires a different part number — mismatched doors won't hang correctly and can void enclosure structural ratings.

This door set is the right call for enterprise datacenters doing a phased NetShelter SX refresh where airflow compliance is a requirement and row density makes full-swing doors impractical — particularly in colocation environments converting to hot-aisle containment without replacing the enclosure frames themselves.
